Using a large cookie scoop, scoop a ball of dough.
Use your thumb to press an indent in the center of the scoop, making room for the ganache and the marshmallows.
Place 5 mini marshmallows inside of the center. Press down into dough making sure NOT to penetrate the top of the dough ball. You need the dough to cover the marshmallow completely.
Next, place a ganache ball on top of the marshmallows.
Use more dough to cover the marshmallow and ganache and seal the cookie shut. If you do not properly seal the cookie, the insides will ooze out in the oven!
Continue to scoop until all of the dough has been used.
Line a cookie sheet with parchment paper and preheat the oven to 415 degrees.
Bake cookies for 10 minutes leaving at least 4 inches between dough balls on sheet. Let the dough balls that are not cooking, sit in the freezer while you wait.
Remove cookies from oven and place decorative marshmallows or peppermint candies on top! Let cool until set (about 10 minutes). Enjoy!
